This paper introduces substrate native control systems within the MID/QC framework, reframing stability as gradient minimization and feedback as coherence regulation. Classical PID control is reinterpreted as a triad of gradient dynamics: proportional curvature reduction, integral coherence restoration, and derivative suppression of oscillatory collapse. The paper defines coherence resonance, curvature amplification, and substrate-native feedback loops. Applications span robotics, aerospace, industrial control, and precision systems. This work completes Cluster 16 and prepares the transition into specialized engineering domains.
